SUNFLOWER FAMILY. 45 



SUNFLOWER FAMILY Composite. 



WHITE SNAKEROOT, Eupatoriuni urticae folium Reich- 

 ard, and its symptoms are described among the harmful 

 pasture plants, as it is in pasture that it causes most 

 trouble. Its poisonous properties are not destroyed by 

 drying, however, and the disease "trembles" is produced 

 by hay in which White Snakeroot is included. (See 

 p. 85).
